Gallery of Separation Results
Here, we show several examples of our separation results. In each case, we mention the separation method we have used. In all cases, the scene image is the sum of the computed direct and global images. However, to bring out the details, for some of the scenes we have brightened the direct and global images by a scale factor (between 1 and 2) with respect to the scene image. By clicking on each of the thumbnail images shown below, you can see the corresponding high resolution image.

Blonde Hair: Bidirectional Texture Function
Method : Checkerboard

This video shows the separation results for blonde hair as a function of light source direction (varied from -30 degrees to +30 degrees in steps of 3  degrees, where 0 degrees corresponding to the viewing direction). While the global image varies slowly with respect to lighting direction, the direct component changes more drastically.  MPEG, Quicktime

 
Pebbles : Bidirectional Texture Function
Method : Checkerboard

This video shows the separation results for the pebbles sample as a function of lighting direction (varied from -30 degrees to +30 degrees in steps of 3 degrees, where 0 degrees corresponding to the viewing direction). As the source direction varies, the direct image varies significantly within local regions as the shadows shift and the shading changes. However, the global image varies more smoothly with respect to the lighting direction. MPEG, Quicktime
